they are what i have got in the past with telstra the speeds i get are faster the what they clam and optus doenst believe me when i told i can can get speeds over 10mps(at off peak times) they clam anything over 7.2 is impossable
And i get no packet data lose, i never have line drop outs due to using a good modem but i get minor ping spikes
Once i get credit for 1 of my telsra sims i will post what it can do

On a 50/5 connection for the first time since paying for it in January.

Last November my ISP replaced our modem to handle the new 50Mb speed, we were paying for the mid-range 30/3 package at the time. 2012 rolled around, still not on 50/5. We were paying for 50Mb and getting 30Mb for about 11 months. About 3 months ago they upped packages again to 50, 100 and 150Mb. We were paying for 100Mb and only getting 30Mb. Last month we switched to the cheapest option and only in the last 2 weeks or so did we start actually getting 50Mb. We've overspent by about €110 as a result of it.

I just wanted the faster upload speeds really. 30Mb was fine for me but the 3Mb upload speed was ass. I wish it was 50/10 or something decent.

In New Zealand's case, this is about as good as it gets for household broadband.
Where I live we do have fibre optic cables installed but who I am with (Telescum) don't see any reason to fork out the plenty of money they have to spare unless they can charge an excessive premium for fibre optic compared to the rest of the World.

Most people don't have more than 15Mbps downstream and I'm pretty sure that percentage is based on only downstream.

Here is mine.

Do a test to the other side of the world and you shouldn't get more than 1.5Mbps. You'll see that percentage change then. I suspect it's looking at the entire result database which includes when speedtest.net was started before internet speeds skyrocketed.
